Mavis!: The HBO documentary Mavis! profiles gospel and soul music legend Mavis Staples, from her rise to stardom as part of the Staples Singers, whose Uncloudy Day was the first gospel album to sell one million copies, and her involvement in the civil rights movement, to her still active career as a solo artist. “I’ll stop singin’ when I have nothin’ left to say,” she says. “And that ain’t gonna happen!” Watch the trailer below.
